DELIGNIFICATION OF SUGARCANE BAGASSE WITH ALKALI AND PERACETIC ACID AND CHARACTERIZATION OF THE PULP

open access: yesBioResources, 2010
Sugarcane bagasse was delignified with alkali and peracetic acid in a two-stage process to obtain pulps with high yield and low kappa number. The experimental results indicated that alkali pretreatment prior to peracetic acid (PAA) delignification could ...

Biomass‐Derived Laser‐Induced Graphene: From Precursor Chemistry to Device Integration

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Laser direct writing provides a mask‐free route for converting suitable carbon‐containing precursors into patterned, porous, and conductive laser‐induced graphene (LIG) networks. Although LIG was initially demonstrated mainly using aromatic synthetic polymers, such as polyimide, biomass precursors introduce renewable feedstocks with highly ...

On calcium-related problems in kraft pulping of Eucalyptus dunnii

open access: yes, 2023
Kraft pulping is the most widely used pulping process for producing chemical pulp today. It has been in use for more than 130 years. During the pulping process most of the lignin and part of the hemicellulose are removed from the wood, resulting in an ...

CHARACTERIZATION AND PROPERTIES OF ION EXCHANGERS PRODUCED FROM LIGNIN PRECIPITATED AFTER PEROXYACID PULPING

open access: yesBioResources, 2008
Pulping of bagasse by one-stage and three-stage peroxyacetic acid was carried out. Characterization of the precipitated lignin from the waste liquor of the pulping process was studied using infrared spec-troscopy.
